Embodiment
Embodiments of the invention are described below with reference to accompanying drawings.In the accompanying drawing, identical Reference numeral refers to identical parts to avoid repetition of explanation.The ratio of size is unnecessary consistent with explanation in the accompanying drawing.
With reference to the embodiment of Figure 1A and 1B explanation according to shielded type cable of the present invention.A kind of shielded type cable 1 of parallel twin-core has two insulated conductors 2 that are used for the signal transmission that are arranged in parallel and the whole shielded conductor that covers two eradication edge leads, 2 outsides.Shielded conductor is made of a plurality of screens that have first screen 5 and secondary shielding layer 6 at least, and described screen is made of the multiple conducting wires 5a and the 6a that twine spirally respectively.In addition, if situation needs, can provide the 3rd screen 7 that constitutes by metal tape etc.Thereby armouring 8 is arranged on guard shield layer and inner cable section thereof on the shielded conductor outmost surface.
Insulated conductor 2 for example has such structure, wherein signal conductor 3 has the diameter of about 0.09mm and is made of seven strands of zinc-plated copper alloy wires that each strand diameter is 0.03mm, thereby this signal conductor 3 is coated with such as fluorine resin or poly insulator 4 external diameters and becomes smaller or equal to 0.3mm.First screen 5 is made of about 33 to 43 lead 5a, and for example identical with the lead that is used for the signal conductor 3 and dextrad (left hand laying) of these leads is twined spirally.Here, the lead of screen can the right hand be laid or left hand is laid, and winding direction is known as the opposite winding direction with respect to another winding direction.
On screen 5, be formed with secondary shielding layer 6 and between lead, produce the gap that can cause the shield effectiveness deficiency when preventing when cable crooked or distortion.Screen 6 is made of 38 to 46 leads identical with the lead that is used for screen 5 and twines spirally in the opposite direction with respect to screen 5.The quantity of lead 6a is increased to a certain degree, because the diameter of screen 6 is greater than the diameter of screen 5.By with screen 5 rightabouts on twine the secondary shielding layer, can prevent the chaotic of screen 5 and can reduce because the cable bending causes gap or curling generation.The quantity of lead 5a and 6a can increase according to the external diameter of insulated conductor 2 or reduce.
The 3rd screen is made of the metallic foil that twines, for example the PET band (copper-evaporated PET tape) of aluminum-polyethylene terephthalate (PET) band or copper evaporation.The complete periphery that the 3rd screen is very close to each other round insulated conductor 2, thus can realize thorough shielding.On shielded conductor, twine a polyester belt and form armouring 8 with the guard shield conductor and guarantee the mechanical strength of the shielded type cable of parallel twin-core.
Fig. 2 A and 2B are the views of the pitch of explanation screen 5 and 6.The definition of pitch is to form the lead 5a of screen or 6a twines a circle on insulated conductor 2 fore-and-aft distance.Fig. 2 A shows has pitch P
SThe example that the right hand of=6 ± 1mm is laid.Fig. 2 B shows has pitch P
LThe example that the left hand of=10 ± 3mm is laid.
As mentioned below, the inventor clarified the generation of disconnection or short circuit and constitute first screen of shielded conductor and the pitch of secondary shielding layer between relation.When screen is formed with little pitch, because the winding angle θ of lead 5a and 6a is little, so the winding form can be stablized and shield effectiveness can improve.But shown in Fig. 3 A and 3B, when the multi-strand shielded cable 1 of tying up cable tether (cable tie) 10 grades twists in device, thereby the shielded type cable 1 that for example is in the S position moves to T position generation pulling force.In this case, if the winding angle θ of first screen 5 is little, then pulling force concentrates on the internal signal conductor 3 and thereby owing to expands and shrinkage causes being easy to disconnect along the height of screen 5 on vertically.
In addition, if when the mode that shielded type cable 1 becomes loose with the winding of screen 5 is twisted, it is tight that the winding of screen 6 will become.In this case, if loose screen 5 is strapped in tightly with screen 6, then screen 5 will damage and rupture.Twist repeatedly if having the shielded type cable 1 of the screen 5 of fracture, then Duan Lie lead adheres on the insulator 4 of insulated conductor 2 and promotes to be short-circuited between signal conductor 3 and screen.
When screen was formed with big pitch, it is big that the winding angle θ of lead 5a and 6a becomes.In this case, when shielded type cable 1 bending, lead 5a and 6a are easy to sink into confusion, have reduced shield effectiveness.But in this case because along the longitudinal expansion and shrinkage reduce, when tension is to shielded type cable 1, but the part conductively-closed layer 5 that is applied to the pulling force on the signal conductor 3 share, thereby can reduce the disconnection of signal conductor 3.In addition, when twisting on the direction that shielded type cable 1 is making the winding of lead 5a become loose, loose degree is less relatively, although thereby first screen tightly fetter by secondary shielding layer 6, the disconnection of lead 5a also can reduce and rare short circuit.
According to the present invention, shown in Figure 1B, be positioned at the spacing that the first inboard screen 5 is formed with 7-13mm at least.The spacing that secondary shielding layer 6 forms is equal to or less than the spacing of first screen 5.The winding direction of lead in first screen 5 and secondary shielding layer 6 can be same to each other or different to each other.
In traditional shielded type cable, the difference of the spacing of the spacing of first screen 5 and secondary shielding layer 6 is less usually or be about 6 ± 1mm at the most, thereby because the short circuit that the disconnection of the fracture of screen 5 and signal conductor 3 causes is easy to generation.In the present invention, be positioned at the spacing that the first inboard screen is formed with 7-13mm by making at least, the disconnection and the short circuit between screen 5 and the signal conductor 3 that can reduce signal conductor 3 are interrupted.
Although be configured to the situation of 5-7mm compares with spacing, setting the pitch of first screen for 7-13mm be wrapped in is unsettled to a certain extent, but be out of question basically because the confusion of screen 5 can by with the first screen rightabout on twine the secondary shielding layer and be prevented from.Even secondary shielding layer 6 twines on same direction, the confusion of first screen 5 also can be twined screen 6 by the spacing that is no more than screen 5 with spacing and be suppressed.In addition, the 3rd screen 7 that is made of metal forming can be set.In this case, owing to further realize shield effectiveness, so although screen 5 is formed with the spacing of 7-13mm, shield effectiveness can not reduce yet.If spacing is not less than 13mm, then twine and will become unstable, cause the difficulty of producing.
Fig. 4 is the view according to the embodiment of wire element of the present invention.Wire element 11 has the preformed size and dimension that can help connecting up and is equipped with many according to parallel double core shielding cable 1 of the present invention, at least the one end is provided with connecting terminal part 14 (wherein cable 1 is arranged in the plane with preset space length, and has removed its insulating coating of predetermined length in some cases) and is used for being connected with the connecting terminal of massaging device.Wire element can have the structure that shielded type cable 1 and for example coaxial signal cable of another cable are used in combination.
In wire element 11, a plurality of parallel double core shielding cables 1 can have the cable section tied up 12 overlapping with cable tether 10, for example, can also have wherein many parallel double core shielding cables 1 at contiguous connecting terminal part 14 places arranges in line to form the banded aligning part 13 of required band shape.Connecting terminal part 14 can comprise electric connector or be processed into (for example, the processing by shielded conductor be connected with ground connection processing) that having can permission and electric connector or the easy terminal shape that is connected of connecting terminal.
